FOOT-OPERATED DOOR-FASTENER.

Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed October 27, 1917. Serial No. 198,889.

-To all whom it may concern:

Be it known that I, ADnIsoN B. OARLL, a.

citizenof the United States, residing at New York, in the county of NewYork and State of New York, have inventeda new and useful F cot-OperatedDoor-Fastener, of which the following is a specification.

The invention relates to a footoperated fastener for doors; and has forits primary object to provide a device of this character which willenable the door to be fastened at its bottom withoutnecessitating'actuating the usual end bolt employed for this pinpose,and, on the closing of the door, the "15" -moving to a locking position.

A further object of'the invention is the provision of a fastener of thischaracter wherein the particular mounting thereof upon the door enablesit to clean the socket or keeper recess from dirt, or other foreignmatter, which would interfere with the movement thereof.

latching of the door, and, in this manner, the

secure fastening of the door is assured without inconvenience on thepart of the opera-' tor of said fastener, the latter being weighted forthe gravitation thereof when thrown to locking or'unlocking position,so. that the same will be sustained in suchpositions on passing apredetermined point in the pivotal A still further object of theinvention is the provision of a fastener of this character which isextremely simple in construction, thoroughly reliable and eflicient inits operation, strong, durable and inexpensive to manufacture.

Other objects will be in part obvious, and

in part hereinafter pointed out.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts, which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings- Figure 1 is a fragmentary verticalsectional view through a door frame or casement base or sill, with aportion of a door in elevation, showing the fastener constructed inaccordance with the invention applied, the fastener by full lines beingshown in looking position, and by dotted lines inunlocking position.

Fig. 2 is a fragmentary vertical transverse sectional view thereof.

Fig. 3 is a view similar to Fig. 2, showing a slight modification of theinvention.

Fig. is'a detail transverse sectional view through the bearing for thefastener shown in Figs. 1 and 2 of the drawing.

Similar reference characters indicate corresponding parts throughout theseveral views of the-drawing.

Referring to the drawing in detail, A designates a portion of a door,and B a portion of a sill or base of a door frame or casement, which areof the usual wellknown constructions, the same being fitted with thefastener hereinafter fully described.

The fastener comprises a bearing including a base plate 5 formedcentrally thereof, with a hollow lug or boss 6 which projects outwardlyfrom one side thereof, and this bearing is secured in any suitablemanner to the inner face of the door A at or contiguous to the loweredge thereof, the bearing in this instance being fastened by the usualscrews 7, and passed through the base plate 5 and engaged in the door.

Pivotally supported upon the bearing'is the latching member, whichcomprises a hub 8, formed with a latch ear 9, and a pair of ofisetfoot-engaging wings 10 and 11, respectively, on'the ends of arms whichare spaced from each other and extend radially from" said hub 8 inangular relation to one another and also with respect to the latch ear9,, the hub'S being journaled upon the boss or lug 6, and held thereonby means of a wood screw or other equivalent member'12, which: 1

is passed through the hollow'boss or lug 6 and engaged in the door.

The boss is longer than the width of the hub and extends beyond the sameat one side, so that the head of the bolt or screw 12 does not bear uponthe latching member, and this serves to kee the latter free to rotatewith no loosening tendency on the screw.

The boss also forms a stiff axle on which the latching member swingsfreely, taking all "bending tendency off the bolt or screw andpermitting said bolt or screw to clamp the plate firmly to the door.

Countersunk within the base .or sillB of the door frame or casement injuxtaposition .to the bearing, is a keeper formed from a body 13 havingan intermediate elongated substantially arcuate-shaped recess or socket14: for receiving the latching ear 9 when moved to locking position, thekeeper being vfitted within'the'ba'se or sill B so that theupperside-thereof will be substantially flush with'the top face of saidbase or sill, and is "fastened in any suitable manner.

The recess or'socket being formed in the -ke'eper plate, is'metal-lined.Moreover, the

pivot of the latching member is located at a point above the transversecenter of the recessor socket, which is of'a length and width so thatthe sweep of the ear'of the latching memb'er'rreaches practically theentire area thereof, whereby the ear'serves to keep the recess or socketclear and free from ice, snow 'and" accumulations of dirt and trash.

Mounted in or integral with the base plate 5-of the hearing at theproper pointthereon,

i'i's astop'projection'15, with which contact the foot-operated wings 10and 11 in the .rniovement of the latching member to its two:positions,.so'that the same will be-limited in 1 such movements.

' By attaching the stop pin or projection to the 'abase plate, a bettercommercial article is provided, which is more readily applied ztothedoor.

v The f'oot operated Wings 10 and 11 are disp'osedin such a manner as tooverbalance the -member after reaching a predetermined :Qpbmt "in itspivotal movement for the gravi- --'tation of said member either tolocking position or unlockingposition. "On moving the 'latchi'n'gmemberto locking position, the ear 9 thereof will'enter the recess 14 in thekeeper and a positive locking of the door will be In Fig.8 ofthedrawing, there is'shown a slight modification of the invention,wherein the door has mounted transversely therein 7 a tubular sleeve 16,the ends of which slightly project beyond the face of the door and aresurrounded by facing or escutch'eon plates 17 Passed through the sleeve16 is a spindle 18, preferably square in crosssection throughout a majorportion of its length,

while the'end's'are threaded to receive nuts 19, working against washers20, mounted 'Gopies'ot this patent'may be obtained for upon said ends,and,"in this mannenthe hubs 21 of apail of foot-operated members 22 and23, respectively, are fastened to the spindle 18. The member 23 isconstructed identically 'to the latching member hereinbefore described,while the member v22 .is similar thereto with the exception that thelatching earis eliminated or dispensed with, the member 23 beingdisposed at the inner side of the door, while'the member 22is loc'atedatthe outer side of the door. It=-willbe2obvious that the fastener canbeaaetuated from either 'tions and modifications may ":be made in theinvention, such as xcome prOperIy'WIthIn the scope of the appendedclaim, without '"departing from the spiritiofthe invention, orsacrificing anyiof its: advantages.

From the foregoing, :it "is thought that the construction and operation:of the invention will :be clearly understood, :and therefore. a moreextendedexplanation-has been omitted.

What is claimed is .A'device rof the character described, comprising alocking member having: a latching ear, means for pivotallyzmounting'themembernpon a-doorso'thatthe eariszmovahle in the arc of'a circlebelowthebottom edge :of thezdoor, and a keeper placed directly rbelow thelocking member when the latter is in its locking position, and having an'arcuateshaped recess in the :Lp'ath of the latching .ear and receivingthe same, the portion of-said ear operating within the recess havingplane faces, and said recess having a 'curved'botapart greater than thethickness 'of the car, so that the earinits movement serves to keep therecess clean.

In testimony, that Iclaim the fore ageing as my own, I have heretoafiixed mysi'gnatur in the presence of two witneses.
